高淀粉高粱05-1高产技术措施研究

Research in High Yield Production of 05-1 High Amylum Sorghum

为了配合高淀粉高粱05-1的大面积生产,试验采用三因素二次回归311A最优设计,从种植密度和施肥量两个方面进行了研究,建立了高淀粉高粱05-1产量与施肥量、产量与密度的数学模型,得出了05-1在晋中平川地区种植的最佳密度为10.8482万株/hm2,最高产量施肥量为纯N 195.6 kg/hm2,P2O591.3 kg/hm2,K2O 150.04 kg/hm2。

This optimum design of 311A is used in this test which coordinate the abundant produce of 05 - 1 high amylum sorghum. It has been conducted from two main technology aspects： cultivating density and applying fertilizer have been studied, and it has built density a mathematics model which is the high amylum sorghum 05 - 1 output amounts, and output and the density mathematic model, have reached 05 - 1 the best density cultivating in Jin Zhong City level land area with applying fertilizer 108.482 thousand stubs/hm^2, maximum output fertilization application amounts are pure N 195.6 kg/hm^2, P2O5 91.3 kg/hm^2 and K2O 150.04 kg/hm^2.
